E46 2002 330Ci wiring harness for power driver seat with memory

I am selling a brand new OEM wiring harness for E46 2002 330Ci power driver seat with memory. $80 including delivery.
Or even better: If you live in Chicago area near Naperville IL, stop by and I will swap the harness for you as you watch it, for $120 (including the harness). $40 for my hard work Repair time approximately 1 hour.

The reason why I have this part for sale: when my driver power seat quit moving, I removed it and found out that bunch of wires within the harness snapped after 10 years of moving seat up/ down/ forward/ backward and constantly rising & folding the seat forward to allow passengers in and out of rear seats (the car is a coupe). I re-terminated the wires but the seat was still dead... Then I purchased and installed brand new harness, - AND THE SEAT WAS STILL DEAD! Then it hit me like a train to check FUSE # 65 (Adjustment Driver Seat, fuses are located in the passenger side glove compartment). Sure enough the fuse has blown. This usually happens when wires start kinking, and because of the low wire resistance, the fuse blows on circuit over current, as designed. If your passenger power seat is still moving, the quickest way to check that IT IS the fuse and NOT wiring harness is to remove fuse #70 (Adjustment Passenger Seat) and put it in place of fuse #65. If driver seat starts moving after that, IT IS FUSE.

So after a stop at Autozone and $8 for set of two 30A fuses, the driver seat works just fine with original, repaired harness. And brand new harness is for sale

Life starts just after 7200r.p.m.
